Tips. 1  Full-grown Chihuahuas generally don't get to be above 6 to 9 inches tall. 2  If yours is taller than that, either as a puppy or an adult, he may be a mixed breed. 3  Don't use color as an indication of your dog's breed, as both short-and long-haired Chihuahuas can come in practically any color.

Factors Affecting Wave Speed. The speed of any wave depends upon the properties of the medium through which the wave is traveling. Typically there are two essential types of properties that affect wave speed - inertial properties and elastic properties.
How fast do waves travel? The speed of a wave-its wave speed-is related to its frequency and wavelength, according to this equation: wave speed (metre per second) = frequency (hertz) Ã wavelength (metre). For example, a wave with a frequency of 100Hz and a wavelength of 2m travels at 100 Ã 2 = 200m/s. Check your understanding of the equation by having a go at this activity.
